Abstract

Scientific evidences for climate change have been assembled by two main agencies viz., the IPCC
(Inter-governmental Panel on Climate Change and the UN FCCC – United Nations Framework Convention
on Climate Change) based on investigations carried out by a large number of researchers from all over the
world. This heightened activity has resulted in the development of a new branch of science called climate
change science. Following is a brief account of the major evidences reported by scientists to reveal the
existence of climate change. As with any new branch of science, sceptics about climate change also abound,
but these groups are being pushed into a corner by the increasing evidences.
